Previously I use Dorico to type English matters in most case. Now I deal with things written in Japanese, and I found that certain OpenType features are necessary. I would like to see future releases of Dorico (maybe since Dorico Pro 4) support all East-Asian OpenType features listed on this webpage:
I personally need the following:
- Proportional Widths (pwid)
- Proportional Alternate Widths (palt) // Necessary if typing a Chinese article with condensed Japanese paragraphs quoted inside.
- Proportional Kana (pkna) // Only certain Japanese fonts support this function. Source Han fonts only support ‘palt’.
I believe that ruby texts (furigana) in Japanese is also necessary.
Here is a reason of supporting proportional Japanese typography: You westerners may not want to see every texts typed in your language displays in full-width monospaced format. This is how Japanese texts look like without the proportional kana.
P.S.: One more thing related to Western language typograpy: I do believe that some of those who use Georgia may want lining figures in lieu of oldstyle figures, hence the necessary of supporting ‘Lining figures (lnum)’.
